文摘
- •
Ca-doped α-Fe2O3 nanotubes were synthesized by a simple electrospinning method.
- •
Grain size of the samples is significantly affected by Ca contents.
- •
Ca-doped sensors exhibit enhanced responses toward both ethanol and acetone.
- •
A sensing mechanism is proposed based on the grain refining effect of Ca dopants.
